I am not a fan of stable coins, because of several reasons. First of all, 90 percent of them are centralised. Secondly, what is the point of holding a stable coin, because it does not bring you any benefits. But if you want to invest in a stable coin, it should be DAI.
Even I am not a fan of stable coin as there is no point in buying and holding stable coins but that's not the purpose of stable coins as they are mainly used to convert your crypto asset post trading to avoid any loss as the value tends to fluctuate. I use stable coin just for conversion purpose like most of us do.
